Se distribuye tanto sobre dunas costeras como tierra adentro. En el trabajo se aplicaron cuestionarios y se realizaron entrevistas entre pobladores de San Isidro y Colonia La Mancha, en la costa de Veracruz. Una nueva especie de bolitoglossa caudata: La Victoria, Departamento de Caldas, m.

Una nueva especie de Bolitoglossa Caudata: Plethodontidae de las selvas del Magdalena Medio en Colombia. La Miel River, Mpio. The new species is mainly recognized by the presence of a robust body, extensively webbed hands and toes, a brownish ventral chromatic pattern with small darker brown and cream dots, non-protuberant eyes and a relatively large size.

Estos resultados indican la influencia de las precipitaciones en el crecimiento radial de C. Infestation parameters and indexes of ectoparasites associated with each sex of Oxymycterus rufus Fischer are compared.

The similarity between both sexes according to their ectoparasites was of The results obtained show that host sex may influence on the prevalence and mean abundance of those ectoparasites which in previous studies have showed preference for O.

Field work was conducted between June and October A total of species belonging to 13 orders and 34 families were recorded. Six species were classified as very abundant, 10 as abundant, 20 as common, 32 as uncommon, and 37 as rare; 79 species were permanent residents, 28 were winter visitors, 2 summer visitors, 3 transients, and 5 were local migrants; 15 species were classified as endemic to Mexico, and 23 are marginalitsa. The bird composition of Sabino Canyon mainly resembles the avifauna the Balsas river basin.

Dalla Selva alla Cupola: The numerous supply contracts and payments allocated to the haulage margina,ista reveal the route followed by wooden materials from the forest marginalizta building yard and allow the identification of the various types of labor involved in the felling of trees, the preparation of logs and their transport. These documents specify the amount of timber ordered from each hauler and, in some cases, even the linear and volumetric dimensions of the wooden elements ordered by Opera.

Such information has permitted the formulation of hypotheses about the structure and dimensions of temporary wooden scaffolding. The resolutions of the consuls of Wool Guild and the Opera wardens regarding the forest administration testify to the existence of a bureaucratic structure charged with overseeing the woodland heritage. Impacto del abonamiento integral en el rendimiento y calidad de fresa Fragaria x ananassa Duch.

The norteadora question of the research was to know that type of ambient management is made by the hotels of selva?

Foi used as instrument of collection of data the questionnaire, that if subdividiui in four great subjects to be searched. The first one was relative questions to the planning of the place, margialista to to the profile of the customer, third to the room and the marginalisfa questions architecture the building subject relative questions to the energy resources and infrastructure of the public services.

As result of this analysis was concluded that two of three hotels searched are practising management ambient of form less impactante, since type of construction adopted until services offered to guests, or either shows objective that its hotel is coadjuvante for customer that visits this type of place, that stops it does not import luxury, comfort and amenities, more yes contact with the fauna and flora and way of life of the natives.

Nazi biopolitics and the dark geographies of the selva. This article examines the spatialities of Nazi genocidial practices. Although the historical events that we recall have been. The state of Oaxaca, in southeast Mexico is home to an extraordinary biodiversity. But human activities have led to significant changes, including reduction of different natural habitats, especially tropical forests, so it is important to document the diversity of these environments, and their response to the anthropocentric changes.

Therefore, this study aimed to estimate the diversity of terrestrial mammals in a tropical forest in escuwla of the state of Oaxaca, Mexico.

Three transects were walked to search for tracks, catches of organisms, sightings, and phototrapping from September to August There were recorded 15 species of 6 orders, 11 families, and 14 genera, 7 of this not previously known in the region.

Trophic and microhabitat niche overlap in two sympatric jarginalista from La SelvaCosta Rica. At this site, both dendrobatids are sympatric due to the introduction and naturalization of D. Despite the progress made during the past 20 years, searching dendrochronological potential in tropical and subtropical tree species, tropical dendrochronology, is still in a development stage. The aim of this research was to determine the potential of C.

The tree-ring anatomical characteristics were carefully examined and we were able to develop a year tree-ring chronology and correlate it with precipitation records. The tree-ring chronology was developed based on 47 series of 27 trees.

Tree rings are clearly delimited by large pore diameters in earlywood and small ones in latewood associated with marginal and paratracheal parenchyma. The tree-ring chronology was related to precipitation records from Satipo and significant correlations were found with the previous rainy season and late dry season of the current growth period. Moreover, we found close relationship between tree growth and total precipitations of the hydrological period December to September for the interval These results demonstrate the influence of rainfall at different stages of C.


The good discrimination of annual rings, strong relationship with precipitation, the wide range and longevity of trees years make C. Los resultados reportaron que Los predictores utilizados fueron los siguientes: Evaluation of occupancy explains the spatial distribution of species in the community and is important to develop conservation strategies. We evaluated occupancy and abundance patterns of nocturnal raptors in 2 sites with different level of heterogeneity landscape structure and composition in the Selva El Ocote Biosphere Reserve.

Through point counts and owl playback callings we estimate occupancy and abundance patterns. We explored possible relationships between patterns of recorded species and structural habitat attributes using generalized linear models. Occupancy and abundance spatial variation was explained by structural habitat characteristics i. Cuentos ashaninka del r??

Hydrogeology of the lacustrine system of the eastern margin of the Salar the Atacama Chile ; Hidrogeologia del sistema lagunar del margen este del Salar de Atacama Chile. A hydrogeological conceptual model of the Eastern margin of the Salar de Atacama Chile is proposed taking into account climatic, geological, geomorphological, piezometric, chemical and isotopic data.

The study establishes the processes that explain the hydrochemical evolution of waters from salty groundwater in the alluvial aquifer located in eastern part of basin until brines at the saline aquifer of the Salar. The main processes associated with this hydrochemical evolution are evaporation and mixing, but water-crust interaction in the discharge areas of the alluvial aquifer associated with the saline wedge also modifies groundwater composition, and plays a role in the dynamics of the evaporitic crusts in the Salar.

The existence of low permeability materials near the surface explains the existence of the permanent surface water bodies in the study area. Based on the data collected in the study three different mechanisms are proposed regarding the main sources of water to the lagoons: Los muestreos se realizaron mensualmente desde noviembre de hasta mayo de en tres localidades: Se registraron 8 especies: Lucilia cluvia Walker, Lucilia sericata Meigen, Lucilia sp.

Numerous plant associations are described and grouped together in the following classes: Pistio-Eichhornietea communities of floating cormophytes Xyrido-Typhetea helophytic herbaceous vegetation Polypodio-Tillandsietea epiphytic and comophytic vegetation Ruderali-Manihotetea ruderal and segetal vegetation Andropogono-Baccharidetea savanoid vegetation Rhizophoretea mangroves Lantano-Chusqueetea woody marginal communities of the forest Cedrelo-Ocoteetea rain and mesophilous forest.

Special attention is paid to the study of the physiognomy, structure and dynamism of the vegetation and its biogeographical significance.
